Speedrun

As Krune had said, they really didn't do anything beyond being adrift on the ocean. From time to time, they used fishing nets to capture a large batch of fish. Krune cut them up accordingly, separated the meat from the rest before dumping the remains back into the ocean.

He only collected some useful parts that he thought would come useful later. Well, he needed a lot of meat, for he and the Seamstress were consuming through it quickly. The Seamstress was moving through the water in search of any large fishes they could hunt to obtain Godly Points. 

Moreover, she was also moving around to train her body accordingly. After all, the passive ability, Moving Water was incredibly useful. When activated, all it did was generate currents around the body, propelling it forward.
